(Nuclear Engineering))--North-West University, Potchefstroom Campus, 2012.Existing correlations developed to account for pressure drop and velocity distribution in packed beds are not ideal for beds with low aspect ratios. This study investigated a method to model flow distribution through packed columns by performing numerical analysis using an explicit approach.
